Image Comparison Database

I want to set up a site where users can compare two images side by side selected from a list of available images.

For example: I’ve got a portrait named “Woman 1” that is in color and another named “Woman 2” in black and white. Ideally I’d like the user to be able to select Woman 1 in a drop-down box and compare it side by side to another image (Woman 2) also selected from a drop down box.

Should I use WordPress to attempt this? (I’d like to keep it as part of an ongoing blog)

Does anyone have any ideas?

Thanks in advance.
